To get a detailed look at how Facebook’s scraper is interpreting your Open Graph object, use the Facebook debugger. The debugger outputs a list of all the data and resources that Facebook pulls from your Open Graph object.
Open Graph is a protocol that enables any web page to become a rich object in a social graph. It was originally created by Facebook to enable web pages to have the same functionality as other Facebook objects. Control how your content appears when shared
To debug the Open Graph protocol, ensure correct OG tags are implemented, use validator tools like Facebook Sharing Debugger, Twitter Card Validator or our Open Graph tester to identify and fix errors, and clear social media caches to reflect changes.
